On a large multisite i have configuration management installed. But it fails to export large lists of e.g. tracked variables. When i click on the "select all" checkbox and proceed to "export to tar file" the site loads and then gets back to the unselected list offering no download file.
It works when the list is small (e.g. content types).
Nothing in the drupal logs.
Does anyone know why or how to debug this? Is it about memory? I have 1024M enabled on the site.
